Hello there!

Welcome to the latest edition of Twenty Question Tuesdays with TechHub Swansea.

Last week we met Tony Dowling, MD at Team Tock. This week, we turn to David Wragg, a Materials Development Engineer at HiETA Technologies Ltd.

So, over to David and his 20 answers...

1. What is your expertise?

I'm a materials engineer, with a general knowledge of materials science, so the theory and background to how materials are developed and how they are selected, tested and processed. I've worked in lab settings on low cost novel solar cells and now I work with powder materials in additive manufacturing. I'm also involved in quality control, component analysis, manufacturing, testing and design.

2. Tell us what a normal day for you looks like.

As we're a small company with a high productivity, there's not really a normal day to talk about. Typically Mondays are roughly normal:

Monday Morning: Cuppa, followed by checking industry news, world news and email. Monday morning stand up meeting where you talk about what you're doing that week and any support that is needed from colleagues. Check the work log for tasks that need completing in the week/day/month. Check over to do list.

Monday Afternoon: Testing/Reporting/Research/Completing to do list stuff.

My work day varies much more than that - recently I've been away from my desk in meetings or managing small projects, people and testing more than I have been undertaking research or reporting/analysis at my desk.

My work hours also vary, as we are trying to build a successful business with a great reputation and as a result I work the hours I need to, not just 9-5 (though I draw the line at weekends).

3. How long have you been involved in Tech?

I've been involved in Science and Technology as a job for seven years. Both in a research setting and a commercial setting.

4. What does your company do?

HiETA is a design and development company specialising in additive manufactured heat management components and light weighting structures.

Heat management such as heat exchangers and heat sinks. The light weighting of structures involves using organic design or lattices to reduce the weight of components to increase efficiency.

5. What role do you have now and how long have you been in it?

I was employed as a materials and development engineer. Mainly for my knowledge of materials and testing. However, I also have been involved in component testing, quality assurance, health and safety, standard conformance, research, design and development and a few other areas. I've been in this job now for 20 months.

6. How did you end up in your current role?

After finishing my PhD, I sent my CV out to several recruitment websites and consultants. HiETA's recruitment process came across the CV and contacted me to ask if I would like to be put forward as a possible candidate for interview. I had followed additive manufacturing throughout university and was very interested in getting involved in the area, as it involves cutting edge applications and technology. It was also a very different field to that of where I had worked previously, so would be a interesting challenge. The interview process was quite comprehensive and happened in three stages, containing technical and non-technical components. Following this, an offer was made and I accepted it.

7. Whats the most rewarding thing about your job, what makes it all worthwhile?

The challenge. Proving people wrong when they say something is impossible.

8. What are your greatest achievements to date?

I unfortunately can't answer this one.

9. What do you do when you’re not in work?

I'm an avid mountain biker (when I have the time) and enjoy hiking and photography. I'm also in the process of designing and building my own quadcopter for messing around/racing.

10. Which area do you live in and how long have you been living there?

Currently live in north Bristol and have done for about 2 years.

11. What would you like to see happen to your Tech Scene immediately and in the future?

More commercial uptake and interest of additive manufacturing for sure.

12. If you had to recommend one book, film or game to me, what would it be and why?

Book: Hitchhikers Guide to the Galaxy. As it has all the advice you need for life: Don't forget your towel and the answer to life the universe and everything is 42. That's the big questions answered, so you can get on enjoying life.

13. Name three things you would take with you on a foreign holiday.

Hitchhikers Guide to the Galaxy
Walking Boots

14. Mac, Linux or PC?


15. Xbox, PS4, or PC (or other)?

PC. However, I will concede that Halo is awesome on the Xbox and Uncharted is awesome on the PS4.

16. What is your claim to fame?

I'm awesome.

17. If they made a film of your life, who would play you?

It's a tie between Ryan Reynolds and Hugh Laurie.

18. Given the choice of anyone in the world, whom would you want as a dinner guest?

Scarlett Johansson. Or Nikola Tesla.

19. Tell us something about yourself that people wouldn’t expect.

I am insanely competitive.

20. What's your superpower, or what's your spirit animal?

Telekinesis (I wish).


How long has your company been operating?

3 years.

What is your company’s expertise / core product?

Design and Development
Heat engine components
Light weight structures

What are your company's greatest achievements to date?

I can't tell you unfortunately.

What will your company be doing in 5 years time?

More of what we do at the moment, but bigger, better, faster and stronger.

Are you looking for investment?
